MCU 평가를 위한 HILS 시스템 개발

This paper describes implementation and development of Hardware-in-the-Loop Simulation(HILS) system to easily test software functions of Motor Control Unit(MCU) in hybrid electric vehicle. A current automotive ECU has a number of requirements which are legal enforcement, passenger convenience, driver assistance and dynamic drive aspects. These various requirements make the software functions more difficult to enhance reliability. To overcome this problem, this paper presents a better testing environment for maximizing the software quality using the HILS technique. The proposed HILS system can cover not only simulation environment of plant model in real-time but also a means to automatically test the software functions embedded into MCU. For the validation of simulation environment, the experimental results of the developed HILS system are compared with simulation results of the designed plant model on the PC environment. The proposed HILS system will look forward to improving the reliability of software quality and cost-effectiveness of the products.
